Jina

安装要求

pip install -U langchain-community

导入库

import requests
from langchain_community.embeddings import JinaEmbeddings
from numpy import dot
from numpy.linalg import norm
from PIL import Image

API 参考：JinaEmbeddings

通过 JinaAI API 使用 Jina 嵌入模型嵌入文本和查询

text_embeddings = JinaEmbeddings(
    jina_api_key="jina_*", model_name="jina-embeddings-v2-base-en"
)

text = "This is a test document."

query_result = text_embeddings.embed_query(text)

print(query_result)

doc_result = text_embeddings.embed_documents([text])

print(doc_result)

通过 JinaAI API 使用 Jina CLIP 嵌入图像和查询

multimodal_embeddings = JinaEmbeddings(jina_api_key="jina_*", model_name="jina-clip-v1")

image = "https://avatars.githubusercontent.com/u/126733545?v=4"

description = "Logo of a parrot and a chain on green background"

im = Image.open(requests.get(image, stream=True).raw)
print("Image:")
display(im)

image_result = multimodal_embeddings.embed_images([image])

print(image_result)

description_result = multimodal_embeddings.embed_documents([description])

print(description_result)

cosine_similarity = dot(image_result[0], description_result[0]) / (
    norm(image_result[0]) * norm(description_result[0])
)

print(cosine_similarity)
